DETAILED DESCRIPTION OF AN ENABLING EMBODIMENT

As shown by an embodiment of the invention in FIG. 1, the hands-free device mounting arm apparatus 10 includes a waist belt 12 with a mounting plate 14 attached thereto. A first cable housing assembly 16 is secured to the waist belt at the mounting plate. An adjustable, tubular arm 18 houses a cable and is attached to the first cable housing assembly 16 at one end and a second cable housing assembly 20 at the other end. A pivot support assembly 22 is connected to the second cable housing assembly and acts as a base for a device 24 attached thereto.

The waist belt 12 has a tall, rear center support section 26 and at least one side support section 28. Two end sections 30, 32 can be connected through an attachment mechanism 34 to create the front section of the belt. The center support section 26 and the side support section 28 are rigid to counter the weight of the tubular arm 18 and attached device 24. The combination of the high center section 26, the support side section 28 and the support plate 14 provide a unique combination that not only supports but also helps to balance the forces applied by the arm and attached device.

The majority of the apparatus components are shown in an exploded view in FIG. 2. The cable 36 has a first end 38 and a first bead stop 40 and a second end 42 and a second bead stop 44. A rigid tubular section 46 provides the base of the tubular arm as is connected at one end to the first cable housing assembly. Referring to FIGS. 3-10, the tubular base 46 contains a curved section 48 and a straight section 50. A flange ring 52 fits into an opening in the first cable housing assembly to connect the tubular arm to the assembly. A flared end 54 is utilized to connect the top of the tubular arm to an adjustable tubular arm segment 56. A plurality of tubular arm segments 56 may be used as necessary. A tubular end segment 58 provides the connection for the tubular arm to the second cable housing assembly 20.

To begin assembling the components, a user could feed first bead stop 40 (and first end of the cable) through the top opening of the second cable housing assembly 20 and through the attached tubular end segment 58. The cable could continue to be threaded through the tubular arm segment(s) 56 and the rigid tubular base 46 where it exits below the base. The first bead stop is then fitted into a cable retention sleeve 66. The cable retention sleeve is then seated within the bore 62 of the elongate body 60 of the first cable housing assembly. The cam lock shaft 64 (with the cam lever 65 attached) is then inserted through the openings in the elongate body 60 and the retention sleeve 66 aligned therein. A retention component (lock ring) is typically used to hold the cam lock shaft in place.

After installation of the first cable end into the first cable housing assembly has been completed, the cable tensioning nut 70 can be adjusted to take up unnecessary slack in the cable. This nut on the threaded tube 68 positions the second cable housing 20 relative to the tubular end segment 58. After adjustment, there will still be some cable slack left. This is taken up when the cam lever is eventually activated to hold the cable and tubular arm in the position desired by the user.

The pivot support piece 72 can now be placed over the second cable housing. The ring seats 78, 80 of the forks 74 of the pivot support piece are placed in alignment with and on the outside of the radial protrusions 71 of the second cable housing. Once aligned, the rectangular pin shaft 82 can be inserted through the aligned components of the pivot support piece and second cable housing until the first end of the pin shaft 84 exits the pivot support piece and the second end of the support shaft with the external teeth 84 are seated and mated with the internal teeth 98 of the second ring seat 80. The spring 81 and plunger ring 83 can be positioned and secured in place with a screw 85 threaded into the end of the rectangular pin shaft.

The mounting/pivot plate 86 can now be positioned over the annual post 76 of the pivot support piece 72. The pressure cup 90 is positioned within the pivot support piece and a threaded bolt 92 inserted until it exits the bottom of the annular post section 72. A nut 94 is threaded onto the bolt for securing the components in position. The mounting posts 88 of the pivot mounting plate provide the alignment and securing components for mating with the openings in the base 96 of the attachable device 24

The mounting plate can be secured to the waist belt by any acceptable means. The illustrations show the plate riveted to the waist belt at the side support section 28. Similarly the first cable housing assembly can be secured to the support plate by any acceptable means also. An embodiment of the invention could actually have a side support section and the mounting plate integrated as one piece. In that embodiment, the side support section would also serve the function of a mounting plate.

The device 24 to be supported needs to be attached to (or have as a component) a base 96 with openings that align with the mounting posts 88 of the pivot mounting plate. Suitable devices are too numerous to list but include stands, cup or beverage holders, music stands, portable electronic devices, etc. The mounting of the base 96 to the pivot mounting plate utilizing the mounting posts is illustrated in FIGS. 14-18. The base 96 is aligned over the posts and with the flat surfaces of the two components touching, the base (and any attached device) is slid toward one side to secure the base and pivot mounting plate in the proper position as seen in FIGS. 15 and 16. The base is slid back to the original position to disengage the two components.

The assembled apparatus has several degrees of freedom to allow for varied positioning of the attached device 24. The rigid tubular base 46 can be rotated 360 degrees about axis A1. Axis A1 is coincident with the center of the elongate body 60 of the first cable housing assembly (FIG. 1). Each tubular arm segment (56 for example) can be rotated approximately 30 degrees off the axis coincident with the adjacent tubular arm component. Tubular arm segment 56 shown in FIG. 10 can be rotated about axis A2 which is the axis that is coincident with the axis of the straight section of the rigid tubular base 46. The tubular end segment 58 can also be rotated approximately 30 degrees off of axis A4, the axis coincident with center of the adjacent tubular arm component as shown in FIG. 10.

The pivot support assembly 22 can be rotated approximately 300 degrees around axis A3 (FIG. 12), the axis coincident with the center of the rectangular pin shaft 82. In addition, the device 24 can be further rotated approximately 30 degrees about axis A5 (FIG. 12), the axis coincident with the center of the annular post 76 of the pivot support piece 22.

To begin to place the apparatus for proper usage, the rigid tubular base 46 would be rotated to achieve the desired position and the lever 65 would be moved from the unlocked position (FIG. 8) to the locked position (FIG. 9). The movement of the lever would move the cam shaft 64 and cause the cable 36 to be taut, thus fixing the rigid tubular base 46, the tubular arm components, and any device attached thereto, if applicable, in their relative positions. The tubular arm segments that are rotatable can be adjusted manually and the tautness of the cable will keep them in their newly adjusted position. It is possible to release the cable tension slightly via the cam lock lever and adjust the rigid tubular base and/or the tubular arm segments in the desired positions before tensioning the cable again.

The pivot support piece 72 (and any attachments thereto) can be rotated about the rectangular shaft axis by depressing the head of the screw 85 and compressing the spring 81. This will push the rectangular pin out from the second ring seat 80 and disengage the external gear teeth 84 from the internal gear teeth 98 thus allowing the pivot support piece to rotate.

The pivot mounting plate 86 can be further rotated by loosening the adjusting nut 94 and rotating the pivot mounting plate into the proper position. Tightening the adjusting nut 94 will then secure the pivot mounting plate in the desired position.

FIGS. 14-18 demonstrate a quick-connect assembly of base 96 of device 24 to mounting plate 86. The mounting posts 88 of mounting plate 86 as aligned with corresponding slots in base 96. The base can be a separate component or the base of the device to be attached. The mounting plate 86 and base 96 are shown partially assembled in FIG. 15. FIG. 16 shows a detail section plan view taken from FIG. 15, without the hook portion of post 88, showing the interlocking detent features of a post 88 and a slot in base 96. The mounting plate 86 and base 96 are shown fully assembled in FIG. 17. FIG. 18 is an elevation section view, taken from FIG. 16, showing post 88 detachably engaged with plate 86.

GLOSSARY

Cable: A portion of metal, composite or suitable material having a length and a cross-sectional area. The material properties of the cable must provide strength and durability and not be subject to excessive linear deformation (such as stretching). A cable will typically have a length and a diameter but it is feasible that a cable could have a length and not a diameter, such as in a rectangular cable.

Rigid Side Support: The waist belt shown and described herein includes a side support section that conforms to the side hip or waist area of a user and is rigid enough to counteract the forces of the remaining components of the device mounting apparatus (and device) attached thereto. The rigid side support can have a rigid mounting plate attached thereto or have a mounting plate incorporated into the rigid side support.

Tubular base: The tubular base segment of the tubular arm is rigid and has a curved section and a straight section. Any suitable material can be used to provide the tubular base with the required rigidity.

CONCLUSIONS, OTHER EMBODIMENTS, AND SCOPE OF INVENTION

The illustrations show embodiments of the invention utilized to carry out the intended purpose. However there are modifications that fall within the scope of the invention.

As disclosed, the side support section of the waist belt can be rigid so that the first cable housing assembly can be mounted directly thereto. In another embodiment a separate mounting plate can be utilized between the side support section of the waist belt and the first cable housing assembly.

The tubular base segment of the tubular arm is rigid and has a curved section and a straight section. The rigidity and configuration of the tubular base provide this vital component with the properties necessary to allow the apparatus to maintain its position when the apparatus is deployed for use or positioned on the user in a stored position. Any suitable material can be used to provide the tubular base with the required rigidity to operate effectively. The rigidity of the tubular base is also essential to provide the support necessary to allow the cable to be tightened to hold the apparatus and device in position.

Embodiments of the invention provide at least three degrees of rotational freedom of the device mounting assembly and any device attached thereto. The rigid tubular base 46 can be rotated 360 degrees about axis A1. Tubular arm segment 56 can be rotated approximately 30 degrees off of axis A2. The pivot support assembly 22 can be rotated approximately 300 degrees about axis A3. This allows great flexibility of the position of a device that is attached. For example, an electronic device with a screen can be positioned vertically to face the user and then easily adjusted (rotated approximately 90 to 150 degrees) about axis A3 to face towards and provide access to another for review and a signature, for example.

These three degrees of freedom provide great maneuverability of the device mounting plate 86 and any device attached thereto. An important feature of these embodiments is the ability to store the apparatus in a fixed, solid position against the user's chest or to the side when not in use. In other words, the use of the cam lever and cable tensioning allows the apparatus to have solid structural support along the whole length of the cable.

Another axis of rotation A4 is utilized when a tubular end segment 58 has a rounded end to allow it to rotate (approximately 30 degrees) about A4. The addition of tubular arm segments can provide further axes of rotation if desired or required.

A final axis of rotation A5 runs through the center of the annular post 76 of the pivot support piece 72. An electronic device (or a paper form) can also be rotated approximately 180 degrees about axis A5 to provide access to another person (facing the user, for example).

In one embodiment detailed herein, a cable tensioning nut 70 is utilized to take up unnecessary slack in the cable. In another embodiment the cable tensioning feature in the second cable housing assembly is eliminated. In this case, the cable would be sized to the correct length so that only the cam lock lever would be needed to adjust the position of the cable and allow the tubular arm components to be locked into position.

The above description presents the best mode contemplated in carrying out the invention. However, it is susceptible to modifications and alternate constructions from the embodiments shown in the drawings and accompanying description. Consequently it is not intended that the invention be limited to the particular embodiments disclosed. On the contrary, the invention is intended to cover all modifications, sizes and alternate constructions falling within the spirit and scope of embodiments of the invention.
